Make PCs Greener

Wouldn't make a difference actually, he would still only be using 300w or so. ;)
A more powerful psu does not make any difference to the pcs power usage.

Yeah I think he knew that and was waiting to slate him :p

But a 520W PSU would probably be more efficient at the 300W mark so it would save energy. ;)

Say for example a PSU is 80% efficient at 80% usage and 70% at 70% usage (which is about right for most quality PSU's) then you would get this (using power consumption of about 420W):

The 520W PSU would use 503W to power the PC

The 600W PSU would use 546W to power the PC

So the 600W uses mor power to power the same computer.

--------------------------------------------------------------


And I worked out the average PC would use about 150-200W if on 24/7, which to me sounds about right. :)

A PC using 150W on 24/7 will use 1,314KWh and produce 2.5 tonnes of CO2 to run. (over the 3 years)

Oh and a TV on standby 24/7 will use less than 35KWh per year (releasing 22Kg of CO2 per year for the electricity) whereas using your microwave to cook for 10 minutes day uses 50kwh and releases 32Kg of CO2...

2.5 tonnes for 1 average PC? :|

If they stuck modified kinetic movements, like those found in watches, to chavs feet we could harness the power of them running from the plod! :p
 
If the UK population cut out ALL carbon emissions, and I mean, down to the physically impossible zero, the effects of this would be negated by China alone (not even mentiong India) in a few years.

Why, therefore spend millions upon millions trying to solve a problem that will happen anyway? I read with dismay the other day how the UK had bought loads of rotting veg in Thailand I believe to offset our emissions.... clap. clap.

Yep it's all a load of nonsense :)
 
We're very small contributors in the grand scale of it, reducing our emissions isn't going to do much at all.
 
Seriously not C02 again. Arghghghghg I wish everyone would just shut up about carbon emissions becuase in the grand scheme of things they simply DO NOT MATTER.

Every time we faff around being ecowarrior, China builds another power station rendering our efforts totally pointless.

NOTHING we in the UK can do will make the blindest bit of difference. If we all scrapped EVERY car tommorrow, the difference to global carbon emissions would be so slight it wouldnt even register.
 
Make new prisons with human sized hamster wheels generating electricity.

That will get rid of the obese, ease the prison crisis and provide electricity.
 
I don't post much but I just had to with this, and no I ain't no tree loving hippy before anyone gets any ideas.

Turn things off you lazy bunch of gits. Saves yourself money and saves the environment at the same time.

We might only produce 1 tonne over 3 years, for one PC, each, so not a lot you might think. Hmm but wait theres millions and millions of PC's in this country alone. Heck lets take the forum population, currently 23,984, thats 23,984 tonnes of CO2 less over 3 years. But how many of us have more than one computer? I bet its rather a few, I know I do. Then if you factor in everything else, TV's, Consoles, lights, heating etc etc before you know it the population of this forum has reduced the CO2 output by maybe 30-40,000 tonnes over 3 years. And theres only 24,000 of us.

As soon as you start thinking in terms of the entire population of the UK and then the world you soon realise just how much of an impact we could all make. If we just generated electricity through green methods, or something like fusion, fantastic lets leave everything on but we don't.

And why do we do it, cause we're lazy, we can't be bothered to wait a few mins for our computers to turn on. Thats no excuse, stop being lazy and start having an impact, if you ain't using it turn it off, save yourself money and the environment.

EDIT: But yeah lets put the prisoners to work, giant hamster wheels all round for inmates, that should help :D
